Feverfew is the common name of a perennial plant native to America and Europe, found near hedges and in waste places. It is allied to the wild chamomile, but has flat leaves and smaller flowers. The stem has many branches, is about two feet high, and has a strong aromatic smell. It was so named from its use as a medicine in treating ague and fever and is still used as a tonic and stimulant. A double flowering species is cultivated in gardens and a related plant yields the Persian insect powder
